Supported Upgrade Paths

An upgrade consists of deploying r12.0 SP2 components to an existing SiteMinder environment. Upgrading to r12.0 SP2 can be accomplished in two ways:

Completing a migration.
Configuring a parallel r12.0 SP2 environment beside an existing environment. Both environments use one or more key stores to maintain single sign-on.

If you are upgrading from r6.x, both upgrade paths are supported.
